3 terms and definitions
The following terms and definitions apply to this document.
3.1
Residue carbonresidue
The residue formed by the evaporation and pyrolysis of the sample under the conditions specified in this section. The value of the residue to the sample of the mass fraction
Said.
4 Method summary
A sample of the sample was weighed and heated to 500 ° C in an inert (nitrogen) gas stream for a certain period of time. Then the sample
The vials are placed in a desiccator and then weighed to calculate the residual carbon residue value.
5 instruments and materials
5.1 trace residue detection equipment see Figure 1. Mainly consists of the following components.
a) raw coke oven. should be able to hold the bottle rack, and can 10 ℃/min ~ 40 ℃/min heating rate of heating to 500 ℃, in the exhaust
The pipe outlet is equipped with a condensing tank. The shape and size of the coke oven are shown in Fig. The coke oven exhaust pipe should be connected to other exhaust systems
On the discharge of oil vapor and the exhaust pipe should not be negative pressure. If this is not met, the instrument should be installed in a fume hood.
b) Vials. made of soda lime glass or borosilicate glass, flat bottom. The capacities were 2 mL, 4 mL, 10 mL, respectively. 2mL vials outside
Diameter of about 12mm, height of about 37mm, wall thickness of about 1mm, its shape and size shown in Figure 3; 4mL vial diameter of about 12mm, high
